By procceding from the all-gaseous state Navier-Stokes equation and using ENO difference scheme,the limited cold-flow jets produced by ignitors are numerically simulated in SRM chamber.Then the flow field structure and characteristics are analyzed.

• 从曲线坐标下的完全气体N-S方程出发,采用ENO差分格式,对点火发动机工作初期,在固体火箭发动机内腔形成的受限冷喷流流场进行数值模拟;在此基础上,分析了喷流的流场结构及特性。
